Question

a potential difference is applied to the player of a capacitor filled with an insulator the energy stores in the capacitor is I the capacitor is disconnected and the insulator is pulled out now. thework done in pulling out the insulator against the electric field is 4U. the dielectric constant of the insulator is

Answer 1

Capacitor: device that stores electric potential energy and electric charge. - Two conductors separated by an insulator form a capacitor. ·
